The Auralic Altair is a roon-ready Streamer / DAC. It’s not possible to use this device as a roon core. You need a computer like a MAC or Windows PC to run the core. I recommend to read this introduction: https://roonlabs.com/howroonworks.html
As Chris mentioned above, the Auralic is a Roon Ready endpoint but it is not a Core device. I recommend checking out our Getting Started Guide for more information on getting started with Roon. If you have any questions about this please let us know!
